In a new interview with ET, Ashley Benson and show runner Marlene King opened up about the transition for the couple.

“I was so sad,” Ashley, 23, shared. “This is the thing, I’m so happy for Tyler, he deserves it so much, but he’s like my other half! He’s just amazing. When the day comes to shoot his last scene, I’m not going to be able to do it. I mean, I don’t want to give him away to these other people.”

She added, “But, I talked to Marlene about [how Caleb will be written off PLL] and I’m excited for people to see that because I’m pretty happy with how she told me their story would end.”

Marlene revealed of the couple’s ending, “Hanna and Caleb are such a great couple and we’ve designed this beautiful Casablanca moment for them. Hanna really gives Caleb permission to leave Rosewood and, basically, go to this other show [laughs]. I hope our fans embrace it as much as we’ve embraced it as writers. That’s important to us.”
